LED Indicators
When the test is started, the run/fail LED on the lamp control board (LCB)
will flash indicating the CPU is executing the test routine. If the LED stops
flashing, an error condition has occurred to the test in progress. The LED
on the control interface board (CIB) is used in certain tests to indicate
status of events with the test.
Note: The CIB test (000) should be performed first. The CIB drives the
servo and stepper systems.

Test 000 - Control Interface Board
The CIB should be tested first since it drives the servo and stepper systems
exercised in the following tests. When test 000 is executed, the CIB
indicator LED is lit if the test passes, and remains lit until another test is
performed.
Test 001 - Pan Servo
When test 001 is executed, the pan motor drives the yoke against the pan
stop in each direction. The yoke continues to pan back-and-forth until the
thumbwheel setting is changed. Failure is indicated if the yoke pans with
jerky movements, too slowly, not at all, or remains against the stop.
NOTE: The code used in the test EPROM’s for tests 1, 2, and 9 is similar
to the code used in the operating system. The luminaire will pan and tilt
similar to the calibration process, and then go into test properly. This
applies to the tilt test as well.
